    Installing Error - Unmount Partition


    I used the live installer Ubuntu CD for 7.04. I have an internal hard drive with Windows installed, and an external USB hard drive.

    I choose the "guided" partitioning system and use the entire external USB hard drive. I am going to dual boot with Windows XP.
    However, it all goes fine until I get to the installation part, this message pops up.

    "The installer needs to commit changes to partition tables, but cannot do so because partitions on the following mount points could not be unmounted:

    /media/New\040Volume

    Please close any applications using these mount points.

    Would you like the installer to try to unmount these partitions again?
    "

    There are two options below it, "Go back" and "Continue". I tried both, but they just go back to the "partitioning" page of the installer.

    I tried manually partitioning the HDD with 5gb root and 2 gb swap, but the same happens.

    Is there any way to solve this?
    Thanks.

    Plug-in External HD and boot from Ubuntu CD. Open Terminal and execute this
    Code:
    sudo fdisk -l
    Post output here.
    It is amazing what you can accomplish if you do not care who gets the credit.

    I entered it into the terminal, and here is what I got.

    Disk /dev/sda: 250.0 GB, 250000000000 bytes
    255 heads, 63 sectors/track, 30394 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot Start End Blocks Id System
    /dev/sda1 1 6 48163+ de Dell Utility
    /dev/sda2 * 7 30392 244075545 7 HPFS/NTFS

    Disk /dev/sdb: 250.0 GB, 250059350016 bytes
    255 heads, 63 sectors/track, 30401 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot Start End Blocks Id System
    /dev/sdb1 * 1 30401 244196001 7 HPFS/NTFS


    Thanks for all your help, I hope it's solvable (:

    Boot up from Ubuntu CD and open GParted ( its in Menu ). Delete sdb1 partition and try to install Ubuntu again.
